FRANCESCO SKERL, 0F DAYTON, OHIO, ASSIGNOR TO THE NATIONAL CASH REGISTERCOMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO, INCORPORATED IN 1906.

Specification of Letters Patent.

Original application filed May 7 1913, Serial No. 766,054. Divided andthis application filed July 18, 1914.

Serial No. 851,758.

To all whom it may concern:

Be it known that I, FRANCESCO SKERL, a citizen of Austria, residing atDayton, inthe county of Montgomery and State of Ohio, have inventedcertain new provements in Ticket-Printing Machines, of which Ideclarethe following to be a full, clear, and exact description.

This invention relates to ticket issuing machines and more particularlyto that class adapted to issue one or more tickets of the samedenomination at machine.

All the patentable subject matter disclosed in this application is notclaimed herein, as this is a divisional application of the originalapplication, filed May 7 1913, Serial No. 766,054.

One of" the "chief sources of loss to the owners of theaters, movingpicture shows, and the like, and also in ticket oflices of elevated,subway and other railways as well as other transportation systems, andin fact wherever tickets are sold and used, is the. dishonesty practisedby ticket sellers in reselling tickets which have been used. To preventsuch dishonesty separate ticket takers are usually employed, but it hasbeen found that this .is not always an effectual check upon the ticketseller, as the employee who collects the tickets can, by collusion withthe seller return them to the seller who can again sell them. Employmentof two or more persons to prevent reselling of used tickets isfurthermore quite an item of expense which, of course, the owners ofsuch places wish to avoid. Various methods have. been devised to preventsuch dishonesty, but most of them are defective inasmuch as they leave achannel by which the proprietor can be defrauded either by one of hisemployees or by the purchaser.

The principal object therefore of this invention is to provide a machinewhereby the above losses can be eliminated as well as the expense ofticket selling employees, still retaining in use a system in which oneor more tickets as desired can be promptly obtained by the purchaser.

It is then an object of this invent-ion to provide a ticket issuingmachine adapted to issue tickets only whengcoins of the proper value areinserted into it, and more particularly to provide such a machine inwhich one and useful Imone operation of the or more tickets as desiredcan be obtained at one operation.

Another object of the invention is to embody in such a machine mechanismfor printing the tickets as they are issued thereby eliminating thecarrying of large num- Patented Dec. 16, 1919.

bers of valid tickets which might at any time be subject to theft anduse.

While this is not essential to the broad in- 'ention, manipulative meansare employed 1n the machine shown which are adapted to cooperate withthe inserted coins to control the issuing of the tickets and theoperation of the machine. The means has taken the form of a series ofkeys but other manipulative means may be employed instead, such as anadjustable lever.

It is, too, an object of the invention to embody in such a machine,totalizing mechanism in which the total value of coins insorted in themachine is caused to be accumulated.

Other objects for the specific construction disclosed are to provide forpreventing depression of a key until a coin of proper value is insertedin the machine, and for comletely preventing operation of the machineuntil both the proper coin is inserted in it and the corresponding keydepressed. These have been accomplished in part by provision of twodetents, the movement of one of which permits the locking of thedepressed key and unlocks parts of the machine, while the movement ofthe other. closes the coin slots to prevent insertion of more coinsuntil the operation of the machine is completed.

The machine has been shown as capable of operation from a motor as wellas from a crank and an additional object of the invention is to provideimproved connections between the motor and the machine proper wherebythe duration of operation of the motor and machine is controlled fromthe keys to determine the number of tickets to be issued. .lVith theseand incidental objects View, the invention consists in certain novelfeatures of construction and combinations of parts, the essentialelements of which are set forth in appended claims, and a preferred formof embodiment of which is hereinafter described with reference to thedrawings which accompany and form part of this specification.

In using a system based upon the herein described machine, when acustomer desires to obtain one or more tickets, a coin, the value ofwhich is equal to the price of one ticket multiplied by.the number oftickets desired, is inserted into the machine. The operation of the keycorresponding to the amount of the coin inserted, through the movementof detents, actuates plates which close the slots against insertion ofother coins and lock the depressed key in its depressed position. Anactuating rack for a totalizer is differentially positioned according tothe key depressed at the same time, and the extent of movement of thisrack also deter mines the extent of movement of a spring actuatedmember, which normally locks the machine from operation. hen this memberhas been differentially moved, the crank handle, if the machine is to beso operated, is turned and the operating mechanism given a number ofcycles of movement depending on the number of tickets to be issued. Ifthe motor, as shown in the accompanying drawings, is employed to drivethe operating mechanism, the locking lever for the clutch connections ofthe motor is rigid with the locking member and will be given a likedifferential setting to control the extent of operation of the motor andtherethrough de termine the cycles of movement of the operatingmechanism. During the first cycle the amount inserted is added on thetotalizer and the depressed keys released, but the slots are closed bythe locking plate to prevent the further insertion of coins until thelast ticket is issued. Upon each cycle a ticket is printed by theprinting mechanism and severed by a knife, and the locking member isreturned one step toward its locking position. When the last ticket hasbeen issued the locking member is rendered effective until the movingpicture shows where the price of admission is 5.

Referring to the accompanying drawlngs, Figure 1 1s a front elevation ofa machine constructed according to the invention with the cabinetremoved.

Fig. 4 is an elevation of the left side of the machine.

Fig. 5 is an enlarged detail View of the printing mechanism.

Fig. 6 shows the arrangement of gearing employed for driving theprinting mechanism.

' Figs. 7 and 8 respectively show the detents employed to operate theslot locking plate, and to releas the key locking plate and certainparts of the operating mechanism.

Figs. 9 and 10 are detail views of the clutch connections of the motor.

Keys 1, 2 and 3 represent the nickel, dime, and quarter keysrespectively which respectively .control the issuance by the machine ofone, two, or five tickets. Three slots 4, one for each key, are formedin a plate comprising part of the keyboard 5 of the machine. As it isdesirable that a coin be inserted into its proper slot before thecorresponding key can be operated a device normally locking the keys andunder the con trol of inserted coins has been provided. To this end thekeys carry projecting lugs 6 which are normally in engagement with theextreme ends of notched dogs 8 fast on shafts 9. These shafts aresupported by frames 10 and 11 which are suspended from the keyboard 5 ofthe machine. On the same shafts, but laterally of the machine andbeneath the coin slots, are rigidlv mounted arms 13, each of which has anotch 11 normally located over a pin 15 projecting from the frame 11,and engages at its upper side with one end of a compressed spring 16which, at its other end, is secured to a pin 17, also projecting fromthe frame 11 (Fig. These arms are so constructed that the upper endsproject slightly into the path of coins inserted in corresponding coinslots so that when the coin is inserted it rocks the adjacent arm 13and, by reason of the latter being rigid with its supporting shaft 9,and therefore with the dog 8 supported thereby, causes the latter to bemoved about its shaft to carry its extreme end 7 from engagement withthe lug 6 of its adjacent key so as to permit depression of the latter.By this construction only the kev corresponding to the slot in which thecoih has been inserted is unlocked for depression.

The machine is provided with two detents 18 and 19 adjacent to the rowof keys, and the detents are supported at their lower ends 20 byindividual arms 21 (Fig. 2) loose on a rod 22 projecting from the frame10. The under sides of these arms contact with springs 23, one for eacharm, which are backed by the frame of the machine and yieldingly actagainst the arms 21 to hold the detents in their normal upper positions.The detent 18 (Figs. 2 and 7) is employed to actuate a sliding plate 24(Fig. where- 33 projecting from the plate 24 for the coin slots,slidably mounted on the under side of the casing 5 by slot and pinconnections.

" This plate is provided with slots of the same shape as those in thecasing 5 and with which they normally coincide so that coins can beinserted through them into auxiliary guideway's 34 leading to a commoncoin guideway 35. When the coins have been barely inserted into theauxiliary guideways 34 of the machine, if they are not frictionally heldby engagement with arms 13, they are retained in the guideways 34 bypins 15 projecting from the side of the auxiliary guideways, andopposing arms 37 pivoted at 38 and normally held with their lower endsagainst pins 39 by arms 40 pivoted at 41 to the sides of the frame. Thearms 37 and pins 15 are normally so close together that coins can passbetween them only when the arms 37 are released by their arms 40* andallowed to move slightly out of the auxiliary guideways under thepressure of the coins.

When a key is depressed after having been released by insertion of acoin in the adjacent slot, the detent 18, due to the contact of roller37 projecting from the side of the key with the inclined surface 42 ofnotch 43 in the detent beneath the depressed key, will be moveddownwardly and the shaft 31, through the lever 26 and the link 29, willbe rocked and thereby the arm 32 will be lowered. This movement of thearm through its engagement in the slot of the lug33, lowers the slidingplate 24 and thereby closes the coin slots against the insertion of thecoins during the operation of the machine. This :poin slot closing plateis held in closing position until the endof the operation of the'- machine by the engagement of the forward end 38 of a lever 39, mounted onthe shaft 40'with a projection 41 on the arm This lever is looselypivoted on the shaft 40 and at its rear end is provided with a slot 42into which extends a pin 43 projectin from an arm 44 mounted rigidly ona shaft 46 to which a ratchet 47 and a stepped plate 48' (Fig. 2) arealso fast. This ratchet and plate and therefore the arm 44 are adaptedto be given one, two or five units of movement dependent upon the keydepressed. as will be hereinafter described. The slot 42 isso-constructed that the first unit of movement of the arm 44 rocks theend 38 of the lever 39 beneath the projection 41 of the arm 32 after thelatter has been moved to close the coin slots, while further movement ofthe arm retains the lever in such posltion. Upon the last return unit ofmovement of the arm 44 toward its initial position, at the end of theoperation of the machine, the lever will be rocked out of lockingposition, and the sliding plate allowed to be returned to normalposition by the return of detent plate 18 to normal position by itssprlng 23.

The other detent 19 is employed to release a device which is employed tolock a key in its depressed position. At its upper end the detent issecured to a bell crank lever of which 49 is one arm. This arm carries ashoulder 50 which normally is in engagement with a projection 51 on onearm 52 of a bell crank loosely mounted on a shaft 40, the other arm 54being secured to the upper end of a pitman 55. The lower end of thispitman is forked and straddles a main drive shaft 56 and carries aprojecting roller 57. The arm 52 at its outer end carries a pro ectingpin 58 straddled by the bifurcated projection of a plate 59, whlch haselongated slots 60 through which pass screws 61, projecting from frame10. This plate is provided with extensions 62 which in turn carryprojecting lugs 63, one of these projections being provided for eachkey. A spring 64, which is secured to this plate and to the frame 10, isconstantly under tension and tends to pull the plate 59 in a downwarddirection, but the engagement of the arm 49 with the projection 51 onthe arm 52, which is connected through pin 58 with this plate, normallyprevents such D1OV- ment. When the key is depressed, however, the detent19 is given a downward movement by the engagement of the roller 37 onthe key in the corresponding inclined slot in the detent and rocks thebell crank supporting its upper end, in a counter-clockwise directionthereby carrying the arm 49 out of engagement with the projection 51.When this is accomplished the spring 64 moves the plate 59 downward andcauses the lug 63 to pass over the lug 6 on the depressed key andthereby hold this key in its depressed position,

As the plate 59 is connected by the pin 58 to the arm 52 of the bellcrank loosely mounted on the shaft 40, the downward movement of thisplate rocks the bell crank counter clockwise to carry the arm 54downward about its pivotal center thus forcing the roller 57 on thepitman into engagement with the periphery of a cam 65. The keys arereleased upon the first rotation of the main drive shaft 56 to which isfast the cam 65 as this cam is soconstructed that the pitman, when thelatters roller 57 is in engagement with it, is given a slight movementin the direction ofits length moving the bell crank pivoted 0n theshaft, clockwise to normal position and hence restoring the plate 59 toits normal position. The spring 23 connected to the detent 19 then movesthe latter to its normal position, the key through the spring 64 coiledabout its shank is redepressed engages first with the inclined face 42of the notch 43 in the detent 18 and gives the locking plate 24 apartial movement before the roller engages the adjacent inclined slot inthe other detent 19 so that a wire or a sharp instrument would be takenout of engagement with the arm 13 should it be attempted to use the samefor rocking the latter to unlock the keys, a shoulder 66 on each dog 8being provided so that the key in such case could only be partiallydepressed .as the lug 6 on the key would engage therewith.

The coin is held in its unlocking position between the pin 15 and thearm 37 so that the key may be operated after the insertion of the coin.When the key is operated and i the coin slots'locked, the followingdevice is employed to release the coin so that the same may pass throughthe auxiliary coin guideways 34 and main guideway 35 into a coinreceptacle (not shown). The arms 37 are loosely mounted on studs 38projecting from the inside of' the coin guideway frame and are held innormal position by the engagement of the arms 40 with shoulders 67 onthe lower ends of the arms 37. In this normal position the arms 37 arealso in engagement with the pins 39 projecting from the coin guidewayframe. Each of these arms 40 is fast to a sleeve surrounding its stud 41projecting from the same frame. Arms 68 are also fast to these samesleeves and at their lower ends are pivotally connected at 69 to a link70. The middle arm 68 forms part of a bell crank to the other arm 71 ofwhich is secured a pitman 72 which at its lower end is bifurcated andstraddles a shaft 73. A roller 74 carried by the pitman rides in a camgroove 75 (shown in dotted lines) in one side of a disk 76 whereby whenthe shaft 73 is rotated, as will be hereinafter described, the pitman isgiven a reciprocating movement and the arms 40 are all rocked upward sothat the arms 37 are allowed to drop out of the paths of coins by reasonof the ends of the arms 40 coming directly in front of curved recesses77 in the arms 37. The coins, with the arms 37 released by the arms 40*,have free passage through the auxiliary coin guideways. 7

An inserted coin cannot, however, pass completely" through the mainguideway to the coin receptacle until the machine is operated, as an arm78 rigidly secured to a sleeve on a rod 79 normally closes the lower endof the main guideway 35 leading to this coin receptacle, but a branchguideway 80 to the exterior of the machine is open when the mainguideway is closed. An arm 81 is fast to the sleeve on the rod 79 and atits outer end is secured to a pitman 82 which, at its other end, isforked and straddles the shaft 7 3. An anti-friction roller 83, carriedby this pitman, rides in a cam groove 84 in the side of the disk 76opposite that in which the cam groove 84 is located and this grooveis soconstructed that at the very beginning of the operation of the machinethe pitman 82 is given such a movement that the arm 78 is rockedupwardly about its pivotal center to open the guideway 35 to the coinreceptacle and to close the branch guideway 80 to the exterior of themachine. This device is employed so that a coin or a counterfeit whichis not of sufficient size to be stopped by the pins 15 and arms 37 willpass directly and before the machine is operated through the mainguideway and the branch guideway to the outside of the machine, thus notbeing deposited in the coin receptacle.

The machine as stated may be either operated by a crank handle or by amotor as desired. The motor shown is one well known on the market, -acomplete description of which is found in Letters Patent of the UnitedStates to Charles F. Kettering, No. 923,857, granted June 8th, 1909, together with Letters Patent of the United States to Charles F. Ketteringand lVilliam A. Chryst, No. 1,144,418, granted June 29, 1915; but it isto be understood that any other type of motor may be employed, as thisparticular type is shown merely for convenience. A clutch connection forthe motor is shown and described, as without such a device thethrowing-of a positive lock into the path of one of the moving partswould cause a great strain on the parts when the locking takes place,due to the inertia of the rapidly moving parts. With the clutch,however, the mechanism may be brought to its home position and the motorallowed to run as long as its momentum will carry it without anyresulting damage to the mechanism. This clutch connection is shown inFigs. 9 and 10. The armature of the motor is on a shaft 85 integral witha worm 86 which meshes with a gear 87 carrying a hollow cylindrical part88 form ing one of the elements of the clutch. The other clutch elementcomprises a plate 89 rigidly mounted on the main drive shaft 56. Fast onthe same shaft 46 to which ratchet 47 and stepped plate 48 are rigidlysecured, are two locking arms 91 (Fig. 2) and 92 (Figs. 9 and 10) thelatter of which is adapted to engage a projection, not shown, movablewith the plate 89 of the clutch, and thereby serves to prevent theoperation of the machine. The ratchet and stepped members 47 and 48respectively are given a differential movement as will be hereinafterfully described.

The connections between the cylindrical part 88 and the cut-awayportions 93 of the plate 89 of the clutch are accomplished by rollers 94moving in the cut-away parts of the plate. The movement of thecylinder88 tends to carry the rollers 94 to the narrower parts of thecut-away portions of the plate thereby firmly binding together the twoparts of the clutch. These rollers 94 are mounted on pins 95 carried bya nearly circular plate 96 mounted loosely on the shaft 56 and capableof a slight movement relative to the plate 89. Plungers 97, shown indotted lines and seated in the plate 89, are spring pressed to normallymove the rollers 94 toward the narrower parts of the cutaway portion 93of the plate. It is clear that when the ratchet 47 and stepped plate 48are rocked that the locking arm 92 will be rocked by the shaft 46 andthe locking end thereof carried away from the clutch. The locking arm 92is also in'the path of a projection on the plate 96 and the withdrawalof the arm will release the plate 96 and permit the plungers to forcethe antifriction rollers to the narrower parts of their containingslots. As the end of the operation of the machine is reached the lockinglever 92 is positively moved back to the locking position of thefigures, as will be hereinafter explained, and the projection integralwith the plate 96 will finally contact with the end of the locking arm92 thereby stopping the plate 96. The other clutch parts, however, moveslightly forward but inasmuch as this forward movement presses thesprings of the plungers 97 and moves the rollers to the wide parts oftheir containing notches, the clutch is thereby disconnected and themachine allowed to stop, although the cylindrical part 88 of the clutchmay remain in motion. The locking relation of the arm 92 with the plate96 might be depended upon to completely arrest the mechanism but anotherdisk 98 is pivoted beside said plate 96 and which is movable with theclutch part 89. A projection 89 on this second disk is adapted to beengaged by a projection on the locking arm 92.

The device which closes the motor circuit is the same as that describedin the aforesaid Letters Patent to Charles F. Kebtering and will bebriefly described here. To accomplish this function an additional plate99 (Fig. 9) is mounted loosely on the shaft 56 and is connected to thedisk 98 by a spring 100 which passes about the hub 1001. The spring isconnected at one end to a pin 101 on the disk 98 extending through aslot '107 in the plate 99 and at its opposite end to a pin 1011 on theplate 99. As shown the plate 99 has a cut-away portion 102 in which isnormally placed an anti-friction roller 103 on the lever 104 pivoted onthe pin 105 which projects from the frame of the machine. The plate 99has fastened thereto a lug 106, one endof which engages in the normalposition of the parts with a third projection of the locking arm 92thereby retaining the spring 100 under tension. When the machine isreleased arm 92 moves from in front of the lug 106 and the spring 100will then throw the plate 99 rapidly around until the pin 101 is reachedby the other end of the slot 107 in which the pin moves. Clearly thismovement of plate 99 will carry the cut-away portion 102 thereof awayfrom the roller 103 on the lever 104 and thereby rapidly rotate thelever around the pivot pin 105. The arm 108 of the lever is adapted toengage the anti-friction roller 109 on the circuit closing arm 110pivoted at 111 and carrying an insulating strip 112 directly over springcontact strips 113. When the plate is rotated the lever 104 rocks andthe spring contact strips 113 are quickly depressed until they engagethe stationary contacts 115 thereby closing the motor circuit. Thiscontact is maintained during the complete operation of the machine andis broken at the end of the operation as the projection on the lockingarm 92 moves downwardly again bringing one of its projections into thepath of the lug 106 thereby stoppin the plate 99. The cut-away portion102 of this plate is opposite the roller 103 and when the depressedportion of plate 98 reaches roller 103 the spring contact strips 113rise, breaking the circuit, and the roller is again in the cut-awayportion of disk 98 and plate 99.

It is clear from the preceding description that in the normal positionof the parts the disk 98 and plate 99 have a cutaway portion oppositethe roller 103, but that when the plate 99 is released by a movement ofthe locking arm 92 the cut-away portion of the plate its thereby carriedaway from the roller and the circular portion of the plate movesopposite the roller. The circuit controlling lever 104 is held inclosing position, until after one or more rotations of the clutch,determined in a manner to be hereinafter explained, inasmuch as thecutaway portions of the disk 98 and plate 99 are on different radiallines. At the end of the desired number of rotations of the clutch,

relative position of the two plates is restored and it is only when bothdepressed portions of the disk 98 and plate 99 are on the same radiallines that the spring contacts-113 may break the circuit.

The crank handle, which can be secured, to the crank rod 116, is gearedto the main drive shaft 56 by the gear 117 on this crank rod meshingwith the gear 118 fast to the rod 118 projecting from the side frame ofthe machine (Figs. 1 and 3), and meshing in turn with the gear 119 fastto the main.

drive shaft. The shaft 73 is driven by the main drive shaft as the gear119 fast to the shaft 73 meshes with the large intermediate gear 118. Asshown the gears 119 and 119 are of the same size so that one rotation ofthe motor rotates each shaft once, but as the gear 119 is twice the sizeof the gear 117 it is clear that two rotations of the gear 117 andtherefore of the crank handle are required to give the requisite onerotation of the operating shaft 56.

This driving mechanism does not of itself quite bring the operatingparts back to home position and the following described device isemployed to accomplish such an end,

(Fig. The lever 120 is pivoted to the frame of the machine by the pin121 and at each end carries an anti-friction roller. The roller on theupper end rides on the periphcry of a cam 122 mounted on the shaft 56,while the roller on the lower end is in contact with the flat end 123 ofa spring pressed plunger 123 mounted on the lug 124. The cam 122 is soconstructed as to gradually depress the spring of the plunger upon itsrotation in the direction of the arrow until the very end of suchrotation, when the upper roller will engage with a nearly radial edge124 of the cam periphery and thereby permit the spring through the lever120 to bring the operating parts completely home.

The invention is also provided with an ac counting mechanism comprisingtotalizer elements 1500, and an actuating rack therefor. The actuatingrack is differentially positioned by the operation of one of the keys.During the first cycle of movement of the operating parts the totalizeris rocked into engagement with this actuating rack and the actuatingrack is then restored to normal position, whereby the value of the coininserted into the machine is added on the totalizer. This actuating rack125 is given one, two, or five units of movement depending upon the keydepressed. To this end the keys at their lower ends carry projectingpins 126 which, when the keys are depressed, engage with the lower sldesof inclined slots 127 in plates 128 pivoted on pins 129 projecting fromthe frame, 10. The plate 128 cooperating with the five cent key, ispivotally connected at 130 with the end of a link 131, the other end ofthis link being pivoted at 132 to an arm 133 fast to a stub shaft 134loosely journaled in the frame 10. The plate 128 cooperating with theten cent key is pivotally connected at 135 with a link 136, the otherend of which pivotally connects also at 132 with the arm 133 rigidwith'the shaft 134. The plate 128 cooperating with the twenty-five centkey is rigid with an arm 137 pivoted at 138 to a link 139 connecting itat 140 with an arm (not shown) rigid with the actuator shaft 134.

' The parts just described are so constructed that the actuating rack125 will be given its differential setting corresponding to the amountrepresented by the key depressed as wardly projecting arm 143, pivotedat 144 at its lower end to one end of pitman 145, the other end of whichis bifurcated and straddles the shaft 73 and has a roller 146projectinginto a cam groove 147 of a disk 148 rigid with the shaft 73.This cam groove is so shaped that the totalize'r, through the pitman 145and frame 141, is rocked into engagement with the rack at the beginningof the rotation of the disk 148 and remains in engagement until near theend of the first rotation of it. While the totalizer is in such positionthe actuating tack is restored to normal position and its differentialsetting is imparted to the totalizer elements. This is accomplishedthrough a short pitman 149 (Fig. 2) which is pivoted to the plate 128for the ten cent key at 150 and carries a roller 151, which is broughtinto engagement with the cam 152 (shown in dotted lines) carried by andrigid with the shaft 7 3. This cam is so constructed that after thetotaliZer has been rocked into engagement with the actuating racks thepitman 149 is given an upward movement, thereby, through the plate 128,link 136, and the arm 133, restoring the actuating rack to zeroposition. The totalizer is then rocked out of engagement with the rackby means of the cam 147 through the links 145 to the totalizer frame141. This oscillatory movement is given to the totalizer upon eachrotation of the shaft 73 and constitutes an idle movement after thefirst'rotation, as the actuating rack, as just explained, is restored tozero position upon the first rotation of this shaft and the totalizer isat the end of each rotation disengaged from the actuating rack.

The totalizer is constructed similarly to that shown and described inLetters Patent of the United States No. 570,196, issued October 27th,1896, upon an application filed by Fayette Barnard. The wheel of lowestorder is actuated directly by the actuating rack 125, and is providedwith alternating ciphers and 5s and is arranged to transfer to the wheelof next higher order at each second unit of movement while the wheels ofthe higher order transfer after each complete rotation. Carryingoperations from wheels of lower order to wheels of higher order areaccomplished by the well known Geneva stop transfer mechanism, asindicated in Fig. 1.

Interposed between the shaft 1511 and the several registering wheels aresuitable devices for causing the shaft when turned to pick up the wheelsat different points at which they may be standing and carry them totheir zero positions. This shaft 1511 at its left end carries a disk1521 having in its periphery a single notch with which cooperates thepin 153 on the arm 154. The disks 155 are pivotally supported by sidearms 156.. When the shaft 1511 is turned eration of the machine.

the pin 153 rides on the periphery of the disk 152 and when theregistering wheels are restored to zero position a pin 157 on the diskengages with an arm 158 thus preventing further movement of the disk.Finally, the arm 158 is rocked by its spring action to normal positionas described in the aforesaid Barnard patent.

The device which determines the number of tickets to be issued will nowbe described. In general it comprises a locking member adapted to begiven a differential movement dependent upon the coin inserted and thekey operated, and operative means whereby the locking member is given areturn movement of one step toward locking position as each ticket isissued. This locking member includes the arm 91, which is fast to theshaft 46, and has at its lower end a projection 159 which is normally incontact with the radial edge 160 of the cut-away portion of a disk 161which is rotated in the direction shown by the arrow upon op-- To'thesame shaft 46 is rigidly secured the ratchet 47 which carries ratchetteeth 162 and also the stepped member 48 carrying stops 163 whose construction will be hereinafter described. lVhen the motor is attached thelocking arm 92 for the latter is also fastened to this shaft 46 so thatwhen the locking arm 91 is given an extent of movement the locking lever92 will be given the same extent of movement. A spring 164 is coiledabout the shaft 46 and one end of this spring, which is under tension,is fast to the side frame of the machine, while the other end passesthrough an opening in the segment ratchet gular recess in the under sideof the upper end of link 169, pivotally secured at 172 to an arm 173,which is fast to the shaft 134 on which the totalizer actuating rack 125is rigidly mounted. VVhe-n the totalizer actuating rack isdifferentially positioned, as'has been explained, the link 169 is givena corresponding extent of movement downwardly which differentialdownward adj ustment of the link causes, through the connection of thelink 171 with the pawl 166, the pawl 166 to be taken out of engagementwith the foremost stop of the plate 48 and differentially positionedaway from its normal position. The stops 163 on the plate 48 are soconstructed that the distance between the arcs swept over by points ofthe adjacent stops is equal to one unit of movement of the pawl 166about its pivotal center, so that when this pawl is differentiallypositioned the action of the spring 164 will rock the plate 48 to bringa stop 163 into engagement with the pawl 166 in its differentially setposition, thus differentially setting the plate 48.

When this plate 48 has been differentially I positioned it is necessarythat the link 169 be taken out of engagement with the lug 171, as thetotalizerrack is returned to its initial position at the end of thefirst cycle of movement of the operating mechanism, and this would notbe permitted if the link remained in engagement with the lug 171 on thepawl 166 as this pawl can return to normal position only by a step bystep move ment as the member 48 is similarly moved out of the way. Todisengage this link from the pawl an arm 174 loosely mounted on theshaft 40 and carrying a pin 175 at its outer end, is provided. A pitman176 is also secured to this arm and at its lower end is forked over theshaft 56 and carries a roller 177, which rides on the periphery of anopen cam 178. After the plate 48 has been differentially positioned andat the very beginning of the operation of the machine the cam 178 givesthe pitman 176 an upward movement thus moving the arm 174 with its pin17 5 upwardly to disengage the link 169 from the lug 171 by theengagement of the pin 175 with the lower edge of the link.

The pawl 165 is loosely pivoted on the shaft 40 and is normally held inengage ment with a ratchet tooth intermediate the.

and a lateral wall of the recess 181 in the pawl. The other lateral wallof this recess 181 normally engages with the pin 180 so that when thebell crank, of which 52 is one arm, is rocked about its pivotal centerupon operation of the key, asfully described, the pawl 165 is rocked outof engagement with the ratchet teeth and at the sametime that the pawl166 is rocked out of engagement with the plate 48. It can be seen thatwhen the bell crank, loosely mounted on the shaft 40, is rocked back tonormal position by the cam 178, as has been explained, that the pawl 165will also be returned to normal position and thereby engage one of theteeth of the ratchet plate 47 in its differentially set position.

Means for restoring these differentially positioned members to theirinitial or normal position include a pitman 179 bifurcated at each endtostraddle the shafts 40 and 56. It is given a reciprocating movementthrough a cam groove 1800 in which plays a roller 1800 carried by thepitman. A pawl 182 is pivoted intermediate its ends at 183 to thispitman and at its lower end carries a roller 184, which, through aspring 185 mounted between the upper end of the pawl and a lug inthepitman, is caused to ride on the cam periphery of the disk 186 inwhich the groove 1800 is located. The cam disk 186 and the cam groove1800 therein are so constructed that upon each rotation of the driveshaft 56 the pitman 179 is given an invariable extent of movement in thedirection of its length and at the same time pawl 182 is rocked intoengagement with one of the teeth on the ratchet plate 47 whereby thisplate and the plate 48 is moved so that the pawl 166 engages the nextstop toward the Zero position. The teeth on the segment 47 and the stopson the member 48 are so constructed thatthe pawl 165 engages thealternate teeth of the ratchet plate 47 in moving the plate 48 one unit.When a coin has been inserted into the machine and the key depressed,the pawls 165 and 166 are taken out of engagement with the ratchet 47and the stepped member 48 and these members are thereby differentiallypositioned under the action of the spring 164 by the engagement of thatone of the steps 163 with the pawl 166 that the latter in beingdifferentially set has been placed in the path of. Upon subsequentoperation of the machine the link 169 is disengaged from the pawl 166and the pawl 165 again brought into engagement with the ratchet 47 bythe rocking of the arm 52 through the pitman 55. The

pitman 179 is then given an upward movement in the direction of itslength. and at the same time the pawl 165 is rocked into printing andsevering tickets to be issued by .the machine.

The paper onthe roll 187 is fed by rolls 188 and 189, the former ofwhich is provided with two flanges 190 (Fig. 6), which are of sufficientlength to feed the paper the length of one ticket upon each operation ofthe machine and one rotation. of this roll. The train of gears throughwhich this roll is rotated is shown in Fig. 6. The gear 119 is journaledon the shaft 73 as is the gear 194 which meshes with an idle pinion 195,which is fast to the same shaft 196 as another similar idle pinion 197,which in turn meshes with the gear 198, the latter gear being integralwith the roll 188. The gear 198 is in mesh with a corresponding gear 199integral with the roll 189. The inking ribbon 200 may be fed by thespools 201 by any desired method. The roll 188 is provided with a daterand consecutive numbering device, which are well known on the market,and not described in detail as these details are not essential to anunderstanding of the invention herein described. The inking roll 202inks the type on this dater and consecutive numbering mechanism uponeach rotation of the roll 188. A stationary type block and platen areshown in the drawings but it is to be understood that all of theprinting might be easily done from the rolls 188 and 189 if suitablyengraved. The platen carrying frame 203 is pivoted at one end to theframe of the machine by the pin 204, and at its forward end carries theplaten 205, which is brought into contact with the stationary type block206 at the beginning of each rotation of the roll 189 through theco6peration of the roller 207 which rides in a cam groove 208 in one ofthe faces of the roll 189. After the price of admission has been printedon the paper by the contact of the platen 205against the type block 206the paper is 'fed the length of one ticket and severed by a knife 210.This knife is carried on a frame 211 slidably mounted in a guide in ablock 212 which is fast to the frame of the machine and provided with asuitable co-acting fixed knife edge 213; The frame 211 at its lower endis secured to a lever 214 which is loosely mountedon a stud 208 so thatafter the ticket has been printed and fed a distance equal to its lengthit is severed by the knife 210.

Operation. With the motor attached a complete operation of the machineis effected by a mere depression of one of the keys after the coin hasbeen inserted in its corresponding slot, the coin and the particular keydetermining the extent of the differential movement of the difierentialmechanism, and consequently the number of tickets printed and issued atsuch operation. The insertion of the coin rocks the arm 8 out ofengagement with the lug 6 on the key and permits the depression of thekey. Such depression locks the coin slots by moving the plate 24 throughthe movement of the detent 18, the lever 26, link 29, and the arms 30and 32 and also releases the key locking plate 59 through the rocking ofthe arm 49 out of engagement with the arm 51, the rocking of the arm 49being accomplished through the movement of the other detent 19. Thedepression of the key also differentially positions the actuating rack125 as the rocking of the plates 128 by the keys is imparted to the rackthrough the link connecting the plate with one of the arms fast to'theshaft 134 on which the rack 125 is mounted. The setting of the rackimparts a like setting to the pawl 166 through the link 169. After thispawl is so positioned the pawl 165 being taken out of engagement withthe teeth of the ratchet 47 through the movement of detent 19, themembers fast on the shaft 46 are rocked through the actuating spring 164and thereby one of the stops on the stepped plate 48 is brought intoengagement with the pawl 166. The locking arms 91 and 92 are therebydifierentially positioned and when these parts have been differentiallypositioned the operating mechanism is actuated by the motor or by thecrank handle if the motor is not attached. At the beginning of theoperation of this mechanism the totalizer is rocked into engagement withits actuating rack 125 through the operation of the roller 146 on'thepitman 145 in the cam groove 147 and the amount of the transaction isadded on the totalizer-by the restoration of the actuating rack to zeroposition through the cam 152. Before this rack is restored, however, thelink 169 is taken out of engagement with the lug 171 on the pawl 166through the movement of the pitman 176 by the engagement of the cam 17 8with the roller 177 on the pitman. l

The pitman 17 9 upon each rotation of the operating parts is given anupward movement and simultaneously the pawl 182 is rocked intoengagement with the teeth on the ratchet 47 whereby the ratchet 47,stepped member 48, and the locking members 91 and 92 are moved one steptoward initial position at each rotation of the drive shaft.

Upon each rotation of these parts the platen 205 is brought intoengagement with the stationary type block 206 and subsequently duringthe same rotation the paper is fed the length of one ticket by the feedrolls 188 and 189 and severed by the knives 210 and 213. As the lastticket is being issued the locking members 91 and 92 are given theirlast unit of movement through the pawl 182 on the pitman 179 and themachine, when these locking members are returned home, is locked untilanother coin is inserted and one of the keys has been depressed.
